Abstract: Aspects of the present disclosure are directed to creating virtual doors within artificial reality (XR) universes for traversal within that XR universe and between other XR universes. Users can create virtual doors that control access to their privately owned property (e.g., world, parcel, house, etc.) in an XR universe. For example, an owner of a virtual door can manually lock the door to prevent any user from entering their property through the virtual door. As another example, an owner of a virtual door can configure door permissions and/or privacy settings that serve as heuristics by which a door access control manager determines whether to authorize a particular user, XR world, and/or XR universe to access. The XR universe traversal system can control an execution environment to smoothly transition between different applications, thereby enabling a user to traverse between different XR universes without having to leave the XR environment.

Abstract: Aspects of the present disclosure are directed to systems for capturing, recording, and playing back steps for building objects and structures in an artificial reality (XR) world. A teacher or creator can initiate a capture context within a build mode of an XR application, during which steps (and potentially other metadata) of a building process are recorded and stored. A XR world building engine can generate an interactive replay of the recorded building process that allows another user to view the building process within an XR environment at the user's preferred pace and/or from different perspectives. In some implementations, the XR world building engine can generate a replay of the teacher's or creator's avatar performing the building process, such that the user can view the building process from a third person perspective and perform the same steps to learn how to build objects and structures in an XR world.

Abstract: Implementations can provide a virtual separate space with respect to a virtual venue hosting a virtual reality (VR) experience, such as a concert, a sports game, a meeting, etc., e.g., to replicate the feeling of a side conversation to discuss the VR experience. Some implementations can create a more intimate experience for users viewing a VR experience by providing a quiet, curated space that can be customized, e.g., by changing the look of users' avatars and their virtual environment, without their interactions being observed by others viewing the VR experience at the virtual venue. The virtual separate space can include a moderated version of the VR experience, such as a smaller version of the VR experience with the sounds of the VR experience muffled. Thus, users within the virtual separate space can step away from the VR experience to enter a more controlled environment, while still enjoying the VR experience.

Abstract: In some implementations, the disclosed systems and methods can implement dynamic presentation controls in virtual reality environments. In some implementations, the disclosed systems and methods can customize the activity based on the state e.g., by setting corresponding visual indicators (changing colors, adding 3D models or effects to the artificial reality environment, showing words or emoticons, etc.), changing sound qualities (volume, tempo, applying effects, etc.), supplying haptic feedbacks to the group participants, etc. In some implementations, the disclosed systems and methods can provide groups of artificial reality users (which may be split into opposing teams) common goals to achieve, can monitor user activities toward those goals, and can provide status indicators for progress toward the goals.

Abstract: The present invention relates to a magnetic cooking utensil holder which allows a user to temporarily secure hot pan lids while cooking eliminating the undesirable practice of placing the hot and sometimes soiled lids on a counter top. The device includes a horizontal tubular magnet having a plurality of support legs pivotally attached thereto which expand to form a tripod type support structure. A drip tray for collecting condensate or food residue adhering to the lid is removably attached to a pair of opposing support legs. A pair of opposing side arms each extending from an end of the magnet have a plurality of vertically aligned magnetic strips thereon for receiving additional cooking utensils such as knives, forks and spoons. Accordingly, whenever a user removes a lid to add ingredients or to stir the food within a pot or pan, the edge of the pan is placed within a drip tray with an opposing portion magnetically secured to the magnetic bar.
